In some embodiments, at least a portion of the sound transmission hole 1211 protrudes from the key fitting groove 111 toward the outside of the electronic device 1, so as to prevent the sound transmission hole 1211 from being blocked by the structure of the key fitting groove 111, thereby improving the sound transmission effect through the sound transmission hole 1211. In one embodiment, as shown in fig. 6, sound transmission hole 1211 protrudes completely outside electronic device 1, so as to increase the exposed area of sound transmission hole 1211 and improve the transmission effect of sound through sound transmission hole 1211. In another embodiment, as shown in fig. 7, half of sound transmission hole 1211 protrudes from electronic device 1, so as to reduce the influence of the structure of sound transmission hole 1211 on the appearance of electronic device 1 while ensuring the sound transmission effect.
The following is an exemplary description of the structure and mating relationship of key assembly 12:
in some embodiments, as shown in fig. 8 and 9, the pressing body 121 and the sound guiding structure 122 are separately disposed and movably connected to implement a key function, and the pressing body 121 and the sound guiding structure 122 are separately disposed, so as to improve the processing convenience of the sound transmission hole 1211 and the sound guiding channel 1221.
The key assembly 12 further includes a movable assembly portion 123, the movable assembly portion 123 is connected to the pressing body 121, and the movable assembly portion 123 is movably connected to the sound guide structure 122. Specifically, the key assembly 12 further includes a connecting pin 126, and the movable assembling portion 123 may be an extending rib provided on the pressing body 121, and the extending rib is provided with a strip-shaped fitting hole 1231. The sound guide structure 122 is provided with an assembling hole 1222, the connecting pin 126 is fixedly matched with the assembling hole 1222, and the connecting pin 126 is movably matched with the strip-shaped matching hole 1231. The connection pins 126 may be fixedly connected to the housing 11 after being engaged with the assembly holes 1222 and the bar-shaped engagement holes 1231. Based on the above structure, the sound guiding structure 122 is fixed by the connecting pin 126, and the pressing body 121 can move relative to the sound guiding structure 122 and the connecting pin 126, so as to realize the key function. The movable assembling portion 123 may be fixedly connected to the pressing body 121, or may be integrally formed with the pressing body 121, which is not limited in the present disclosure.
Furthermore, the sound guide structure 122 may further have a mounting positioning groove 1223, the extending ribs are accommodated in the mounting positioning groove 1223, and the assembling holes 1222 penetrate the mounting positioning groove 1223. The extension rib is accommodated in the installation positioning groove 1223, so that the stability of the movable assembling portion 123 in matching with the sound guide structure 122 is improved, and the assembling hole 1222 penetrates through the installation positioning groove 1223, so that the connecting pin 126 can extend into the installation positioning groove 1223 through the assembling hole 1222 to be matched with the extension rib, and the movable matching of the connecting pin 126 and the strip-shaped matching hole 1231 on the extension rib is realized.
In the above embodiment, the key assembly 12 may further include an elastic member 125, an abutting member 124, and a circuit board 127. The elastic member 125 is respectively in elastic abutting fit with the pressing body 121 and the sound guide structure 122, the circuit board 127 is provided with a control circuit and a trigger member 1271 electrically connected with the control circuit, the abutting member 124 is connected with the pressing body 121, and the abutting member 124 and the trigger member 1271 correspond to each other in the extending and contracting direction of the elastic member 125. For example, as shown in fig. 8, the dotted arrow represents the expansion and contraction direction of the elastic member 125, and the pressing body 121 and the contact member 124 can move in the dotted arrow direction as the elastic member 125 expands and contracts. The position of the abutting part 124 and the triggering part 1271 in the extending and contracting direction of the elastic part 125 can be corresponding to: in the telescopic direction of the elastic member 125, a projection of at least a part of the structure of the abutting member 124 coincides with the trigger member 1271, so that the abutting member 124 can realize trigger fit with the trigger member 1271 during the movement. Specifically, when pressing body 121 is pressed, abutting member 124 is in contact engagement with trigger member 1271, and the operation of the control circuit is triggered by pressing body 121 of key assembly 12. At this time, the movable assembly portion 123 moves relative to the sound guide structure 122, and the elastic member 125 contracts. When the pressing on the pressing body 121 is canceled, the elastic member 125 is deformed again, so that the movable assembling portion 123 drives the pressing body 121 to move, and the abutting member 124 is separated from the trigger 1271.
The elastic member 125 provides an elastic feedback effect for the pressing body 121 of the key assembly 12, so that the pressing body 121 can be automatically reset after the pressing is cancelled, thereby facilitating the next pressing operation. The abutting member 124 may be a column structure with a cross-sectional shape matching the structure of the triggering member 1271, so as to reduce interference of the abutting member 124 with other structures inside the electronic device 1. The contact member 124 may be fixedly connected to the pressing body 121, or may be formed integrally with the pressing body 121, which is not limited in the present disclosure.
In other embodiments, the pressing body 121 may be further integrally formed with the sound guide structure 122, and the sound transmission hole 1211 of the pressing body 121 is communicated with the sound guide channel 1221 of the sound guide structure 122 to implement sound transmission. The integrally formed pressing body 121 and the sound guide structure 122 reduce subsequent assembly processes, and simultaneously prevent sound from leaking when the sound is transmitted through the sound transmission hole 1211 and the sound guide channel 1221, thereby improving sound transmission effects.
In some embodiments, the pressing body 121 is provided with a plurality of sound transmission holes 1211 and a connecting channel 1212, and the plurality of sound transmission holes 1211 are communicated through the connecting channel 1212, so that the sound transmission direction of the sound transmission holes 1211 is increased, and the sound transmission effect is improved.
As shown in fig. 10, the connection channel 1212 may be at least one hollow layer disposed inside the pressing body 121, and the hollow layer communicates with the sound guide channel 1221. For example, the connection channel 1212 is a hollow layer inside the pressing body 121, the sound guide channel 1221 is communicated with the hollow layer, and the hollow layer is used as a connection space between the sound transmission hole 1211 and the sound guide channel 1221, so that convenience in communication between the sound guide channel 1221 and the sound transmission hole 1211 and convenience in sound transmission are improved.
In some embodiments, the pressing body 121 includes a pressing surface 1213 and a side surface 1214 bent with respect to the pressing surface 1213, and the sound transmission hole 1211 is fitted to the side surface 1214. The cooperation of the sound transmission hole 1211 and the side surface 1214 prevents the sound transmission hole 1211 from occupying the pressing surface 1213, and reduces the interference and influence of the sound transmission hole 1211 on the hand pressing operation and the influence of the sound transmission hole 1211 on the appearance of the pressing surface 1213.
Further, the side surface 1214 includes a top surface 1214a and a bottom surface 1214b that are oppositely disposed, and a transition surface 1214c connecting the top surface 1214a and the bottom surface 1214b, and the sound transmission hole 1211 is coupled to at least one of the top surface 1214a, the bottom surface 1214b, and the transition surface 1214 c. The sound transmission hole 1211 can be fitted to the top surface 1214a, the ground surface, and the transition surface 1214c, increasing the direction of sound transmission and reception by the sound transmission hole 1211, and enhancing the sound transmission effect. At this time, for example, as shown in fig. 11, the connecting channel 1212 may be two hollow layers inside the pressing body 121, the sound guiding channel 1221 is communicated with the two hollow layers, one hollow layer is a connecting space between the sound transmitting hole 1211 and the sound guiding channel 1221 fitted to the top surface 1214a and the transition surface 1214c, and one hollow layer is a connecting space between the sound transmitting hole 1211 and the sound guiding channel 1221 fitted to the bottom surface 1214b and the transition surface 1214c, so that the sound transmitting hole 1211 and the sound guiding channel 1221 at each position are smoothly connected, and convenience of communication between the sound guiding channel 1221 and the sound transmitting hole 1211 and convenience of sound transmission are improved.
In some embodiments, as shown in fig. 12, the sound guide structure 122 may be substantially cubic, i.e., include three pairs of oppositely disposed surfaces. The sound guiding channel 1221 includes a first opening 1221a and at least one second opening 1221b disposed on the surface of the sound guiding structure 122, the first opening 1221a is correspondingly matched with the sound transmitting hole 1211, and the second opening 1221b is correspondingly matched with the audio module 13. The first opening 1221a and the second opening 1221b can be disposed on different surfaces of the sound guide structure 122, so as to improve flexibility of the disposition position of the audio module 13.
For example, the sound guide structure 122 may include a first face 1224, a second face 1225, and a third face 1226, the second face 1225 and the third face 1226 being adjacent to and perpendicular to the first face 1224, respectively, and the first opening 1221a may be disposed on the first face 1224 and the second opening 1221b may be disposed on the second face 1225 or the third face 1226. As shown in fig. 12, when the second opening 1221b is disposed on the second face 1225, the audio module 13 and the sound guide structure 122 may be in a top-to-bottom stacking matching relationship, so as to optimize the structural sections inside the electronic device 1. When the second opening 1221b is disposed on the third surface 1226, the audio module 13 and the sound guide structure 122 may be left-right fit, so as to avoid the influence of the audio module 13 on the thickness of the electronic device 1, and to facilitate the improvement of the thinness of the electronic device 1.
In other embodiments, the sound guiding structure 122 includes a plurality of second openings 1221b, and the plurality of second openings 1221b are respectively matched with different audio modules 13, and share one sound transmission hole 1211 on the pressing body 121 to implement a plurality of types of sound transmission functions, so as to further reduce the number of external holes on the electronic device 1. The plurality of second openings 1221b may be disposed on the same surface of the sound guide structure 122, or disposed on different surfaces of the sound guide structure 122, which is not limited in the present disclosure.
